Application filed June 6. 1907- Serial No. 377483.

To It whom it may concern: I

llc it known that l, EDWARD L. VOOD, a citizen of the United States, resuhng 1n the borough of Queens, city and State of New York, engineer, have invented a certain new and uselul lmprovcment 1n Faucets, of which the following is a specihcation.

My improved faucet may be used in at great variety ot situations and tor any llllldS, i but it is ntended more particularly for lavatories, sinks and the like, and I shall refer to the liquid as water.

The invention applies to the class in which a valve opens and closes by an endwise move- ;ment,a single puppet. I will describe it as I opened by the long ap 'roved method of forcing it upward from be ow by partially revolving a nozzle in line therewith beneath, and as having a hearing face of rubberi adapted to insurev a tight closure when subjected to a moderate pressure in the direction to close it. tndcr ordinary conditions there is a considerable head of water the pressure of which will insure a tight closing, butother conditions may require assistance. I

have discovered that a very gentle force will attain that end reliably and that it IS practlcable to provide by very siin 10 means not only to press down with gent e force on the valve in addition to-the pressure of the water btit also to serve usefully in limiting the opening movement, in stead ing the valve, and thus avoiding the tentency to rattle which is a fault in'this class of valves as ordinarily arranged, and in compelling the valve j to shut without hammering under any condltrons.

The following is a description of what I consider the best means of carrying out the invention.

The accompanying drawing forms a partof this specification. I Figure 1 is a side view with the nozzle turned into the closed position.

a chamber above, A a tubular'seat for the valve and A an extension downward, screwthreaded on its exterior.

B is the partially revoluble dischargin nozzle screw-threaded on its interior to mate s'crew-threads on A, having a cross-bridge B in its interior and provided with a convenient detachable handle B by which it can be turned at will.

(7 is a stop firmly set in the body A of the faucet and arranged to limit the turning motion of the nozzle.

1) is a top removably set in line with the valve packed as shown and engaged by screwthrcads. its hollow interior is cylindrical, its top helm-spherical.

G is the stem of the valve and H an adjustable lengthener or shoe throu h which the lifting force is received froni t e bridge B, when the nozzle Bis turned in the direction t to open. T here are openings h in this shoe, preferably in the form of open slots, one in each side, which supply an elastic quality to the shoe so that it hu s the screw-threaded j stem within with reliab e tightness even with imperfect workmanship and wear. The upj ong-a iproved construction, I have shown it 5 as me ed with vulcanizedrubber.

is a cu p-sha ped cap tightly set on the upi per end of the stem. v

I The body K of the valve is of such height I thatt'he screw-threaded portion of the stern extends but little above t 1e valve. l M is a ball preferablv of lead or other heavy metal or alloy, of such diameter as to make an easy fit in the interior of the top D. The concave upper surface of the valve-cup L matchc's to this ball. The presence of the ball insures aperfect guidance and steadying of the valve cup .and consequently of the valve.

In cases of extremelylow ressure where the water exerts no appreciablle force to urge the valve down to its seat the ball byits gravity aids to effect the closin The faucet may be (1086f with all the rapidity which is ever required in the most active practice, but it can never hammer, the descent of the ball being always sutiiciently re- I to make the fit easy. The v ve in its turn is held gently to the ball by the closeness of the fit of the valve-cup thereto.

I claim as my invention 1. In a faucet of the up et class, the combination, with a body avmg a valve seat, a valve, and means for raising the valve and releasing and allowin it to sink, of a chamber above the valve, an a loosely mounted member arranged to move up and-down in said chamber, said loosely mounted member being arranged to guide the valve, to limit the extent of its opening movement and to act upon it gravitationally to aid in closing it.

2. In a faucet of the puppet class, the combination, with a body having a valve seat, and fluid passages connected therewith, a valve, and means for raising the valve and releasing it and allowing it to sink, of a chamberabove the valve, and a loosel mounted member arranged to move easi y in said chamber to guide the valve, to limit the ex- I tent of its opening, to act upon it gravitationall to aid 1n closing it and to moderate the ve ocitv of the closing movement.

3. The combination, with a valve body having a puppet-valve seat, a cylindrical chamber in line with and above the seat, and

a screw-threaded extension in line below the I seat, of a partly rotatable delivery nozzle mounted on the threaded extension, means for turning said delivery nozzle, a valve, a valve-stem arranged to be engaged by the delivery nozzle to lift'the valve, a receptacle carried by the stem, and a spherical member mounted loosely in said receptacle and arranged to move in said chamber.

4. The combination, with a valve body having a puppet-valve seat, a cylindrical chamber in line with and above the seat, and a screw-threaded extension in line below the seat, of a partly rotatable delivery nozzle mounted on the threaded extension, means for turning said delivery nozzle, a valve, a valvestem arranged to be engaged by the delivery nozzle to lift the valve and having'an adjustable shoe at its bottom, a receptacle carried by the stem, and a spherical member mounted loosely in said receptacle and arranged to move in said chamber.
